From e8f01a8dad7cdf9ddaa792451733a45ab5d385af Mon Sep 17 00:00:00 2001 From: "Kirill A. Shutemov" Date: Mon, 17 Jul 2017 01:59:50 +0300 Subject: [PATCH] x86/mm: Rename tasksize_32bit/64bit to task_size_32bit/64bit() Rename these helpers to be consistent with spelling of TASK_SIZE and related constants.
